If you selected this option then you have two choices: Electric or Manual Pump. The manual pump is all that you will need however the small electric units are faster and easier to use. You will need to decide which means the most to you cost or comfort.
(Option 1) Manual Breast Pumps
Manual breast pumps are incredibly helpful for moms who only want to pump milk occasionally. They require you to pump the milk with your hands, which can be exhausting if you are pumping milk every day, several times a day. They are very lightweight, portable and cheap, compared to electric pumps.
Pros: They’re cheaper than electric models and don’t need an electrical source or batteries, and often are compact enough to fit in a tote or purse.
Cons: Manual pumps often are slower than other pumps. I recommend these only for occasional use, such as when you’re traveling. or a night out.
(Option 2) Small Electric or Battery-Operated Units
Less work but cost a little more.
Pros: They are relatively inexpensive and portable. With the battery pack, you can pump anywhere, anytime.
Cons: If you want to use this pump frequently, you may find that pumping takes too long. Consider one of these for occasional use only.
